Application nledv December 3,1921. Serial No. 519,589.

To all whom t may concern:

Be it known that I, HENRY BLAIR, a citizen of the United States,residing in San Arde, Monterey County, and State of California, haveinvented a new and useful Improvement in a Railroad Spike, of which thefollowing is a specification.

My invention relates to railroad spikes wherein an anchoring means isarranged to engage the spike to prevent displacement thereof when driveninto a tie to secure a rail thereon.

The primary object of my invention 1s to provide an improved railroadspike.

Another object of the invention is to provide improved anchoring meansadapted to prevent the loosening or withdrawal of the spike' while inservice.

A further object is to provide an anv chored spike that may be readilywithdrawn for replacement of ties or for other purposes when desired.

v A still further object is to provide means vfor facilitatingthe'application of an anchoring means to secure a rail engaging spike inengagement with a rail.

I accomplish these and other objects by means of the device disclosed inthe drawings forming a part of the present specifica.- tion wherein likecharacters of reference are used to designate similar parts throughoutsaid specification and drawings, and in which:

Fig. 1 is a perspective view disclosing the application of my improvedspike.

Fig. 2 is a transverse section of a rail secured upon a tie by myimproved spike.

Fig. 3 is a side elevation of the device as shown in Fig. 2.

Referring to the drawings the numeral 1 is used to designate the shankportion of a. railroad spike provided with a head 2 having a lip 3formed upon the forward side thereof and adapted to engage the flange tof a rail 6 when the shank 1 isv driven into a tie 7 as shown in thedrawings.

An extension 8 i-s formed upon the head 2 and arranged to extendlaterally therefrom to a point beyond the edge of the tie 7, saidextension being preferably slightly up'- wardly bent at its free end asshown in dotted lines in Fig. 3. `The top of the head is substantiallyflat to permit driving of the spike in the usual manner.

A plate 9 having an aperture 11- at one end thereof is arranged toplaced in env gagement with the overhanging end of the extension Sand tobe moved into a position adjacent the side of the tie 7 A plurality oflongitudinally `spaced apertures 12 are formed at the other end of theplate 9 whereby an anchoring spike 13inserted through any one of saidapertures 12V may be driven into the tie 7 atl substantially'rightangles to the spike sha-nk 1. The spike 13 is preferably .pointedslightlyr downward when driven thereby drawing the` extension 8 from itsoffset position into contact with the top ofthe tie 7 as shownvin Fig. 3of the drawings, thereby firmly binding the rail engaging spike invposition and eifectually preventing any loosening'of the spikedue tostresses applied through the rails.

The extension 8 and the apertures lland 12 are so positioned withrespect to the shank 1 that when the spike 13 is .driven the shankthereof will pass immediately back of the shank 1 thereby insuringagainst a rearward movement of the spike such as might permit spreadingof the rails. It is desirable to drive the spike 13 at a point well downupon the tie to provide a substantial thickness of wood thereabove.However, when the ties are closely placed, the driving of the spike 13may be facilitated by driving the same through an aperture 12 nearer thetop of the tie, the head of the spike being thus brought into a positionmore conveniently struck by a hammer.

The extension 8 and the aperture 11 are preferably kmade of rectangularshape thereby preventing any relative turning movement, and the spike 13and apertures 12 being also preferably made of square or rectangularshape for the same reason thereby preventing any pivotal movement of theplate 9 about either the extension or the spike.

The device disclosed in the drawings is Specification of LettersvPatent.Patented 22, 1922..

the preferred embodiment of my invention,

1. A railroad spike arranged to be driven into a tie and having a liparranged to engage the flange of a rail; a laterally disposed eXtensionfrom' the lip arranged to extend over the edge of the tie; and meansengaging said extension for anchoring said spike to the tie.

2. A railroad spike arranged to he driven into a tie and having a headprovided With a lip arranged to engage the flange of a rail and alateral extension arranged to extend over the edge of the tie; anapertured plate adapted to engage the end of the lateral extension; andmeans for securing said plate upon the side of the tie to anchor thespike to the tie.

3. A railroad spike arranged to be driven into a tie and having a headprovided with a lip adapted to engage the flange of a rail to securesaid rail to the tie, and a lateral extension arranged to extend overthe edge of the tie; an apertured plate adapted to engage the end of theextension; and a spike adapted to he inserted through an aperture inthe` plate and driven into the tie to anchor the rail engaging spike tothe tie.

'4. A railroad spike arranged to he driven into a tie and provided witha head having a forwardly extending lip adapted to engage the ange of arail to secure said rail to the tie, and a laterally disposed extensionarranged to extend over the edge of the tie; a plate having an apertureat one end thereof adapted to engage Vthe end of the lateral extension;and a spike adapted to he driven into the tie at right angles to therail engaging spike through an aperture at the other end of the plate toanchor said rail engaging spike to the tie.

A. railroad spike arranged to he driven into a tie and provided with ahead having a forwardly extending lip adapted to engage the flange of aYrail to secure said rail to the tie, and a laterally disposed extensionslightly upwardly bent at its outer end and arranged to extend over theedge of the tie when the spike is driven to bring the lip intoengagement With the rail flange; a plate having an aperture at one endthereof adapted'to engage the end of the extension and having aplurality of apertures at the other end; and a spike adapted to hedriven into the tie at right angles to the rail engaging spike throughone of said plurality of apertures to hold said plate against the sideof the tie and to draw the extension against the tie to anchor said railengaging spike to the tie.

6. A railroad spike comprising a pointed shank adapted to he driven to atie. and a head having a forwardly extending lip adapted to engage theflange of" a rail; an extension fornied upon the head and arranged toextend over the edge of the tie and to rest upon the top thereof Whenthe spike is driven to move the lip into engagenient with the railflange; a plate having an aperture at one end adapted to engage the endof the extension and also having a plurality of longitudinally spacedapertures at the other end adapted to receive a spike diven into the tieat right angles to the rail engaging spike and in engagement With theback of the shank thereof to prevent displacement of said rail engagingspike.

ln Witness whereof I hereunto set my signature.
